Sass sourcemaps only in dev environment

[cachaito]

Hi everyone! This config works great, but how easily turn off Sass source maps feature when i use build task (this settings works on default and build tasks the same)

autoprefixer: {
    options: {
        browsers: ['last 1 versions'],
        map: true
    },
    dist: {
        files: [{
            expand: true,
            cwd: '.tmp/styles',
            src: '{,*/}*.css',
            dest: '.tmp/styles'
        }]
    }
}

Just remove the map option.

(You should also disable sourcemaps in your Sass plugin options.)

Sorry if I was not understood correctly. I have two tasks in Gruntfile.js build and default. In default i need this 'map: true' option but when I'm making a dist package for a client (build task), there is no need for creating .map for .css files.

autoprefixer: {
    options: {
        browsers: ['last 1 versions'],
    },
    dev: {
        options: {
            map: true
        },
        files: [{
            expand: true,
            cwd: '.tmp/styles',
            src: '{,*/}*.css',
            dest: '.tmp/styles'
        }]
    }
    dist: {
        files: [{
            expand: true,
            cwd: '.tmp/styles',
            src: '{,*/}*.css',
            dest: '.tmp/styles'
        }]
    }
}

'autoprefixer:dev' // will call ‘dev’ target
'autoprefixer' // will call ‘dist’ target (default)

Here's more about targets and task- or target-specific options: http://gruntjs.com/configuring-tasks#task-configuration-and-targets

Thank You for detailed answer Dmitry. I just wanted to avoid this syntax while "files: [{...}]" paths are the same for those tasks...

[nDmitry]

Yeah it's not DRY, but Grunt only allows to have common options, everything else must be per target.

You can use a shorter syntax for this particular case though since you specify the same destination:

dist: {
    src: '.tmp/styles/{,*/}*.css'
}

[cachaito]

Again, thank You Dmitry for clearing this case.

Have a nice day!
